CLAMSHELL TELESCOPIC ARM

Clamshell Telescopic Arm

Rope type [Speed-first design]

Printed in Japan

3

Holding Valve (Standard)

Free fall of the clamshell can be prevented thanks to the

telescopic arm cylinder and holding valve at the boom cylinder,

even if piping or hose punctures.

Free-Fall Prevention Device

Dual pull-up ropes and press-down ropes

are utilized to prevent free-fall of the

clamshell even if one of the dual ropes is

broken.

Efficient, Productive Deep-Excavation with the Telescopic Arm

Dynamic Telescopic Actions

Efficient, productive excavation

by dynamic telescopic actions,

using the newly developed

hydraulic system.

Smooth Downhole Excavation

The telescopic arm is narrower than the

bucket to reduce damage to the arm while it

works in a downhole.

Extended Rope Life

The newly designed telescopic arm can significantly extend the

service life of ropes.

Productivity

Rope replacement intervals: 1 800 hours

Free-Fall Prevention Device

Openable Telescopic Arm Top

The telescopic arm top can be

exposed to easily replace a pull-

up rope.

Sliding Cab (standard)

The cab can slide back and forth through Hitachi's original

hydraulic cylinders to let the

operator look down with an

unobstructed wide view for higher

productivity. The long step and

handrails are provided for easy

access to the cab.

Openable Bottom Window

The wide bottom window is openable

to increase front-downward visibility

with less blind area.

Sliding distance: 1 300 mm
